Yes, absence of immediate evidence can be evidence of absence, but not proof. Refutation or denial of a claim is itself a claim, and carries a burden of proof of its own.

There are two ways the word evidence is used: as a synonym for proof or as that which increases the probability of something being true without necessarily being proof. For example in a court of law you need a preponderance of evidence to show that someone is guilty, not just any piece of evidence. This means they evidence in a court of law is not necessarily synonymous with proof.

In the context of empirical investigation, there is no such thing as absolute proof. That is where the phrase is commonly applied. The phrase was most famously deployed in response to the failure to find evidence of aliens and WMDs.

You have evidence that you don't have the means to gather evidence, therefore it is null. It cannot be evaluated.

Also, when its sheer mass is impacting your person it will leave lasting evidence of its existence.

>>10088233
It can be very strong, it depends on context. I would say that the failure to find any evidence of WMDs in Iraq despite years of searching by the UN and the US military is pretty strong evidence of their absence since the probability of years of searching finding evidence if there were WMDs is pretty high.

Bringing up junk like Iraq is exactly what this kind of stuff is for. Look here is some bs math that I'm going to use on dummies to sway their opinion. discovery is made by finding evidence when there was none found before. Evidence is something that you have or do not have. Not something that is or is not. Seems like the majority here can agree that this is bullcrap and should be spread around only if your goals are to make the world a summer place. This garbage is used for politics and to argue whether a god exist. easier to ask the god proponents: "who made god?" That takes the argument that all this stuff can't come from nothing and uses it so they can prove themselves stupid. I am a fan of the idea of god or meaning in life, but you can't just magic and math to battle common sense. If there is some god there has to be an explanation and you can probably make him bleed.

Of course absence of evidence is evidence of absence. It’s just not very strong evidence (let alone proof). People have this strange notion that evidence equals certainty.

Kinda like folks said during that whole Supreme Court thing that there was no evidence of rape. There was evidence, her testimony if nothing else. Now is that convincing evidence? No clue. But it is evidence in the same way that his denial is evidence to the contrary (which wouldn’t be present if, for instance, he never denied it and remained silent on it).

Evidence comes in a variety of strengths and flavors. Just because you have SOME supporting evidence that does not mean that you are right. If you scoured the entire solar system for extraterrestrial life and found none then that isn’t conclusive evidence that there isn’t any but depending on the thoroughness of your search it can be strong evidence.

>Yes, it's also an absence of evidence that the tiger is there.
No there isn't, the evidence isn't like "negative" or something, there is evidence that a tiger isn't there.
If you look and dont see anything, that is positive evidence that it isn't there.
If you've never looked/haven't looked at a sufficient amount of places, then you can't say one way or the other.
Absence of evidence =/= evidence of absence. If you have an absence of evidence you've not looked yet - you have no evidence, which is a string of binary data. If you HAVE looked and there is nothing there, you STILL have binary data, just the data/evidence shows there isn't any of whatever it is you were looking for.
Either way, the data still exists, and that is "evidence of absence" whereas if you don't have any data, that is "absence of the evidence (data)"
These are not the same thing, you can't treat them the same way.

Because of all the other things I've said already.
If I look and find evidence, I have evidence that there is nothing there - I have "evidence of absence".
If I never look/don't look well enough, I don't have evidence one way or the other - I have "absence of evidence".
This is also how we can say that whether or not there are other alien civilizations out there is still up for debate - we have not checked even close to the amount of the universe to sufficiently say one way or the other. We have "absence of evidence". But to say this "absence of evidence" is "evidence of the absence" of aliens, is absurd.

You know there is. SETI and the search for WMDs are not a lack of evidence one way or the other. You're not responding to this because you know your argument fails.

>If I never look/don't look well enough, I don't have evidence one way or the other - I have "absence of evidence".
If I have a dog I have a pet. If I have a cat I have a pet. So by your logic having a dog and having a cat are the same thing.

Also, you need to clarify what you mean by "never look/don't look well enough" in terms of the argument. What is P(A) in this case?

>This is also how we can say that whether or not there are other alien civilizations out there is still up for debate
What about the argument implies it's still not up for debate? Evidence does not necessarily settle a debate. This is simple stuff.

>We have "absence of evidence". But to say this "absence of evidence" is "evidence of the absence" of aliens, is absurd.
It's mathematically proven. It increases the probability of the absence of aliens. Your naive intuition and confusion of evidence for sufficient evidence is not a proof. But I'm glad you finally admitted that SETI is an absence of evidence.

I said it is still up for debate.
We have not checked a sufficient amount of the universe - the amount we've checked is close to 0% (very close to 0%) so we can say we have no evidence one way or the other. If we were to somehow check 95% of the known universe and find no aliens, we have very strong evidence for the absence of aliens.

You said that according to my logic not looking is the same thing as looking and not finding, presumably since they're both absences of evidence. So how is that not an accurate comparison?

>Never looked means not gathering enough data.
What does that mean in terms of the argument? Why are you avoiding the question? If "not enough data" does not increase the probability of B then it is not evidence in the first place and your point is moot. If it does then it is evidence of B and its absence is evidence of the absence of B. It's very simple yet you continue to obfuscate the argument by not clarifying anything.

>I said it is still up for debate.
It's up for debate regardless, since the evidence is weak. What is your point?

>We have not checked a sufficient amount of the universe - the amount we've checked is close to 0% (very close to 0%) so we can say we have no evidence one way or the other.
Close to zero is not zero. Is the probability of SETI finding evidence nonzero, yes or no?

You still don't understand the argument after all this time. It's very simple:

If SETI could have found something that increased the chance of aliens existing, then the fact that it didn't increases the chance that aliens don't exist. Do you agree or disagree?

If the search for WMDs could have found something that increased the chance of WMDs existing in Iraq, then the fact that it didn't increases the chance that WMDs didn't exist in Iraq. Do you agree or disagree?

I don't know about ya'll but proof is only a word that should be thrown around in math or certain trades. Otherwise you are dumbass and are misusing the word. I don't give a fuck if god exists. But the OP algebra is dumb as it will be weaponized in the hands of dummies.

>People say obviously and evidently with interchangeability.
So what?

>A lack of evidence is not evidence.
An absence of evidence is evidence. The proof is right there. If you have an argument against it I suggest you present it, otherwise fuck off.

You seem way outnumbered in your idea of common usage according to the posts on this thread. Do the math. That's ok most people are brainless animals.

You seem to have no response to the basic fact that the phrase is used this way and is well known for its use this way. Reality is not up for a vote.

>LOL. So if "A of B is B of A" is not true in every case, it can't be true in any case? Jesus Christ.
Thats what Abelian means, a group can be abelian. In this case, the group is not abelian.
>Non-Abelian does not mean A * B =/= B * A in every case, brainlet.
Yes it does by definition of a non-commutative group. In this case, English grammar is non-commutative.
"I ate the cow" (subject I, verb ate, object cow) is not the same as "the cow ate I" (subject cow, verb ate, object I) and no pseudo-argument using Bayesian probability (which is, btw, shit compared to Frequentest probability) will change this fact. These sentences are different under Chomsky hierarchy, and therefore you're argument is wrong off the bat. Your only refuge is to go "b-but everyone uses it this way!!" which is both irrelevant, as well as WRONG (as no one but you says absence of evidence = evidence of absence).
>The negation of "every case" is "not all cases" not "no cases."
Obviously. Makes no difference in this case.
>It does by the proof which you have failed to find a flaw in. The only thing you've shown is that you can't do basic logic.
It's not a proof. Stop calling it a proof it makes you look pathetic.
>If SETI could find alien signals in 0.000001% of the universe, then its failure to find alien signals in 0.00001% increases the chance that aliens are do not exist. There is no way around this fact.
No it doesn't.

The distinction has a huge difference

Jesus Christ you're dumb. Abelian requires that for all a, b in A, a • b = b • a. Non-Abeliam requires that for *some* a, b in A, a • b =/= b • a. Example: integers and subtraction is non-Abelian since 2-1 =/= 1-2. Your argument is akin to saying that 1-1 =/= 1-1 since the integers and subtraction is non-Abelian!

>"I ate the cow" (subject I, verb ate, object cow) is not the same as "the cow ate I" (subject cow, verb ate, object I) and no pseudo-argument using Bayesian probability (which is, btw, shit compared to Frequentest probability) will change this fact.
I ate the cow not being equal to the cow ate I has no more bearing on the topic at hand than 1-2 not equaling 2-1 has on 1-1=1-1. The proof shows that the definition of evidence implies that the absence of evidence is evidence of absence. Your utterly retarded non-understanding of Abelian groups is a non-sequitur.

>Obviously. Makes no difference in this case.
Then your argument falls apart since non-Abelian groups can contain commutative elements.

>It's not a proof. Stop calling it a proof it makes you look pathetic.
It's a proof. If It wasn't you would have pointed out the flaw by now.

>No it doesn't.
It does, see the proof in the OP.

>The distinction has a huge difference
It's a proof using Bayesiam probability, there is no relevant difference.

>I've already explained it multiple times
You've explained that you don't understand what non-Abelian means.
